Interesting note - Verizon recognizes that "no camera" is a positive feature for a meaningful number of people. You can explicitly search for phones that have "no camera". You cannot search for a phone that has "No VZNavigator", or "No email", or "No QWERTY Keyboard".

I happen to currently have a brand-new, government-issue BlackBerry 8830. It works well so far, and I like its usability. I don't use the GZNavigator (my agency doesn't have that enabled) but Google Maps can detect "my location" and that works for me. I also like the long battery life.

Windows Mobile 6 is a push technology. Several co-workers are testing devices and they sometimes have trouble synching, and they've complained about battery life. I don't know how that might vary depending on the device though.
